Strata Auckland Airport Scan and Win (Mobile Version Only)
Auckland Airports Strata Club are running a promo with codes around the airport and online.
Each spin gets you up to 500 points = $5 which you can use for coffee and parking etc at the airport.
They have a code on their facebook page - EPCEV which got me $5 off my parking.
If you are at the airport share your 5-letter codes you see, and you can enter them on the mobile version.
